Hi Kalsi,
We bought a a new belt (1975H) and fitted it to our 470c condenser, grooves onto shaft and drum around jockey pulley with spring on left side and there wasnt enough tension, so I swapped the spring onto the right hand side but it has since come off due to too much tension, the belt started to get rubber marbling as it was melting!
After speaking to an engineer it seems there is only one side for the tension spring and we are about to play with the motors positioning. Will let you know if it works, if you manage to find any diagrams/instructions could you be so kind to email them?
Regards
Chris
